Interesting.

This is your own built binary? You could try a binary from
https://johnvansickle.com/ffmpeg/ for comparison.

It can't be an ffmpeg issue, https uses mostly the same code as http,
except for establishing the connection.

I don't know which code causes this, perhaps there's more insight from
"-loglevel debug".

Since you write that curl works, I would guess that a semi-transparent
proxy is choking on ffmpeg's implementation of the protocol, but not
curl's? Or the server's HTTP port doesn't like your source address. Or
something similarly stupid. A tcpdump/Wireshark trace might be
interesting. But try a different binary first please.
